摘要
由于光纤光栅传感器具有灵敏度高、动态范围宽、不受电磁干扰、成本低、体积小等优点,使其在传感领域具有很好的应用前景.光纤光栅传感技术已成为现代传感领域的一个重要研究方向,其在振动传感领域的应用也取得了一定的成就.本文针对悬臂梁式光纤光栅振动传感,将光纤光栅振动传感元件近似为惯性式振动系统,以其数学模型为基础,利用Matlab软件对其传感特性进行了仿真,通过仿真结果,分析了振动传感系统参数对传感特性的影响,并提出了优化光纤光栅振动传感系统的几点建议.此研究对振动传感实验的设计和优化具有理论指导意义.
Fiber Bragg Grating （FBG） sensor with high sensitivity, wide dynamic range, immunity to electromagnetic interference, low cost, and small size, ere, will hold great applicable potentiality in the sensing field. FBG sensing technology has become an important research direction in modern sensing area, and the ap- plication of FBG in vibration sensing has gained some results. This paper mainly discusses the cantilever FBG vibration sensing system. The FBG vibration sensing component is approximated as an inertia vibration sys- tem. The FBG vibration sensing characteristics are simulated by using Matlab based on its mathematical mod- el, and some suggestions are proposed for the FBG vibration sensing system design. The study is valuable for vibration sensing experiment design and optimization.
